Astronaut Robert L. Behnken used a digital camera to take this self-protrait during a spacewalk. Also visible in the visor's reflections are components of the station, the docked space shuttle Endeavour and a blue and white portion of Earth. During the nearly 7-hour spacewalk, Behnken and astronaut Rick Linnehan, installed a spare-parts platform and tool-handling assembly for the Special Purpose Dextrous Manipulator also known as Dextre...

The Strait of Messina Bridge Project, if completed, would stand as one of the landmark bridges of the 21st century. It would be the longest suspension bridge ever built. The Strait of Messina divides the island of Sicily from Calabria in southern Italy, and is 3 km wide. While the overall length is not a big problem, the economics, water depth, wind, and earthquakes all have to be accounted for. To avoid the problem of the deep water, the solution was to design the longest suspension bridge ever...

These two images of the Tuamotu Archipelago, French Polynesia, illustrate diversity in the morphology of atolls, one of the major types of coral reef formations. A typical atoll structure is a lagoon surrounded by a closed rim of cays and shallow spillways that control the exchange of water between the ocean and the lagoon. However, like human beings, this general scheme may vary according to the history of each individual atoll, resulting in a high diversity of morphology, especially for small ...

Covering 6,641 square kilometers (2,564 square miles), Banff National Park lies on the eastern slope of the Rocky Mountains in Alberta, Canada. Banff was the first national park declared in Canada, and the third national park in the world. The park's origin lies in an accidental discovery of a cave containing hot springs in 1883.

The Gulf Stream is one of the strong ocean currents that carries warm water from the sunny tropics to higher latitudes. The current stretches from the Gulf of Mexico up the East Coast of the United States, departs from North America south of the Chesapeake Bay, and heads across the Atlantic to the British Isles. The water within the Gulf Stream moves at the stately pace of 4 miles per hour. Even though the current cools as the water travels thousands of miles, it remains strong enough to moderat...

[movies]Seasonal Swings in Tropical Rainfall: Image of the Day - NASA -- NASA Image Of The Day
Rainfall is the primary way the atmosphere spreads heat around. Not surprisingly, nearly two-thirds of all rain falls in the tropics, where incoming sunlight is steady year round. Sunlight evaporates water from the warm ocean and land surfaces. The water vapor holds on to the heat that drove its evaporation until it condenses back into rain drops and releases the heat back to the atmosphere. This perpetual cycle of heating, evaporation, condensation, and rainfall moves heat from one place on Ear...

[image]Isla San Lorenzo and Isla Las Animas, Gulf of California: Image of the Day - NASA -- NASA Image Of The Day
Located in the northern Gulf of California, Isla (island) San Lorenzo and Isla Las Animas -- part of the Midriff Islands -- record geologic processes involved in the creation of the Baja California peninsula over several hundred million years. If you were hiking southeast to northwest along the 17-kilometer-long (10.6-mile) central ridge of Isla San Lorenzo, you would first encounter granite rocks from the Cretaceous Period (146 to 65 million years ago); this light tan rock occupies the southeas...

[image]Topanga Fire: Image of the Day - NASA -- NASA image by Jeff Schmaltz, rapidfire.sci.gsfc.nasa.gov MODIS Rapid Response Team, Goddard Space Flight Center.
Northwest of Los Angeles, California, a brush fire exploded in late September 2005. Growing to more than 16,000 acres in around 2 days, the blaze threatened homes, natural resources, power lines, and communications equipment in the Thousand Oaks region north of the Santa Monica Mountains. This image of the Topanga Fire was captured by the Moderate Resolution Imaging Spectroradiometer modis.gsfc.nasa.gov (MODIS) on NASA's terra.nasa.gov Terra satellite on September 29, 2005...

[image]Luquillo Mountains, Puerto Rico: Image of the Day - NASA -- NASA Image Of The Day
The Luquillo Mountains are located in the northeastern portion of Puerto Rico, and they rise to elevations of 1,075 meters (about 3,527 feet). The mountains are mainly made up of volcanic rock that was uplifted by tectonic activity between approximately 37-28 million years ago. (Puerto Rico is located between the junction of the North American and Caribbean tectonic plates.) Prevailing easterly winds bring moisture from the Caribbean Sea, which becomes precipitation as the winds cross the mounta...

[image]Larsen Ice Shelf, Antarctica : Image of the Day - NASA -- Image courtesy Landsat 7 Science Team and NASA GSFC
Warmer surface temperatures over just a few months in the Antarctic can splinter an ice shelf and prime it for a major collapse, NASA and university scientists report in the latest issue of the Journal of Glaciology. Using satellite images of tell-tale melt water on the ice surface and a sophisticated computer simulation of the motions and forces within an ice shelf, the scientists demonstrated that added pressure from surface water filling crevasses can crack the ice entirely through...

Unlike Earth the moon does not have air, food and water, so it would take a lot of effort for humans to live and work there, wrote Raina Huang, a student...

[movies]Recession of the Jorge Montt Glacier, Patagonia: Image of the Day - NASA -- Images and animation by Vince Realmuto, based on research by Eric Rignot, NASA Jet Propulsion Lab
A new study of the Patagonia Icefields in South America by NASA and Chile's Centro de Estudios Cientificos concludes the icefields -- the largest non-Antarctic ice masses in the Southern Hemisphere -- are thinning at an accelerating pace, faster than other areas on the planet. The runoff from these melting icefields is contributing to an ongoing rise in global sea level. (Click to read the www.jpl.nasa.gov/releases/2003/138.cfm NASA press release...

[image]St. Lucia Estuary, South Africa: Image of the Day - NASA -- NASA image created by Jesse Allen, Earth Observatory, using Landsat and GIS data obtained from the University of Maryland's glcf.umiacs.umd.edu/index.shtml Global Land Cover Facility .
The Greater St. Lucia Wetland Park is a United Nations World Heritage Site located on the Indian Ocean coast of South Africa near the borders with Mozambique and Swaziland. The park encompasses several different conservation areas (marked with yellow lines) centered on Lake St. Lucia, its tidal estuary, neighboring game reserves, and the St. Lucia Marine Reserve, which extends offshore into the Mozambique Strait (image right)...

[image]Puncak Jaya, Indonesia: Image of the Day - NASA -- Image obtained from the glcf.umiacs.umd.edu/index.shtml University of Maryland Global Land Cover Facility .
The Seven Summits are the highest peaks on each of the Earth's seven continents. However, there is some debate about whether to count New Zealand and Oceania (which adds the Pacific Islands and the Indonesian archipelago) in with Australia. If Oceania is considered as part of the Australian continent, then the tallest peak is Puncak Jaya, also known as Carstenz's Pyramid. Its 4,884-meter-tall (16,024-foot) summit stands well above both Australia's /Newsroom/NewImages/images.php3?img_id=15326 Mt...

[image]Sea Ice Extent in the Arctic Ocean: Image of the Day - NASA -- NASA Image Of The Day
After earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17782 record retreat in September 2007, Arctic sea ice had been making a slow winter recovery. Mean sea ice extent remained at record-low levels in October 2007, but beginning in late October, sea ice grew by more than 150,000 square kilometers (about 58,000 square miles) per day for about 10 days--the fastest regrowth observed in the satellite record...
